Researchers have clocked the fastest-possible electrical switching in magnetite, a naturally magnetic mineral. Their results could drive innovations in the tiny transistors that control the flow of ...

We’re used to thinking of limit switches as a mechanical device that cuts the motor connection before physical damage can occur. [Anthony] decided to try a different route with this project. He built ...

You use limit switches to switch off a motor if it reaches one of its two end positions. Even if you build a microprocessor-based motor controller, you should switch off a motor with hardware by ...

Some engineers, as well as many non-engineers, might be unaware that electrical switches benefit from being lubricated. In fact, for many electrical switches, lubrication is required if they are going ...
